[Discuss-gnuradio] Any clue

[Marcus D. Leech]

Trying to build a fairly simple decoder block, based on gr_block. The 
compile goes OK, but swig goes very badly off the rails:

Can swig only deal with the derived classes? None of the derived classes 
really work for me, since the number of output items is
only loosely correlated to the number of input items, and I may not 
produce any output items until I see a SYNC word on the input.
So things like gr_sync_block don't seem appropriate. Any clues?
